[0029] This specific embodiment is a voice coil reinforcing paper rolling device, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the voice coil reinforcing paper rolling device includes a base 1 and an L-shaped plate 2 fixedly connected to one end of the base 1, a rolling mechanism 3, a pushing mechanism 4, an abutting mechanism 5, and a cutting mechanism 6. The rolling mechanism 3 is used to roll the reinforcing paper onto the voice coil, the pushing mechanism 4 is used to unload the voice coil after the reinforcing paper has been rolled, the abutting mechanism 5 is used to tightly adhere the reinforcing paper onto the voice coil, and the cutting mechanism 6 is used to cut the reinforcing paper.

[0030] Two mounting rods 7 are fixedly installed at the other end of the base 1, a lower fixing plate 8 is fixedly installed at the bottom of the two mounting rods 7, an upper fixing plate 9 is fixedly installed at the top of the two mounting rods 7, and a guide rod 10 is fixedly installed in the middle of the lower fixing plate 8. The top end of the guide rod 10 passes through the upper fixing plate 9 and is fixedly connected to the base 1.

[0031] First, the voice coil is placed on the winding mechanism 3. Then, the reinforcing paper is fed onto the voice coil. The winding mechanism 3 drives the voice coil to rotate, thus winding the reinforcing paper onto the voice coil. During winding, the contact mechanism 5 presses the reinforcing paper against the surface of the voice coil, ensuring that the reinforcing paper adheres tightly to the voice coil. Then, the reinforcing paper is cut by the cutting mechanism 6. After processing, the finished product is pushed out of the winding mechanism 3 by the pushing mechanism 4 to complete the unloading. The whole process is automated, improving production efficiency.

[0032] The rolling mechanism 3 includes a motor mounting plate 301 fixedly mounted on the base 1, first mounting posts 302 fixedly mounted at the four corners of the motor mounting plate 301, a first motor 303 fixedly mounted on the first mounting posts 302, a drive wheel 304 fixedly mounted on the output shaft of the first motor 303, a vacuum shaft 305 rotatably mounted on the base 1, a driven wheel 306 fixedly mounted on the vacuum shaft 305, and a synchronous belt 307 that realizes the transmission connection between the drive wheel 304 and the driven wheel 306. The vacuum shaft 305 has multiple vacuum holes, and the voice coil is sleeved on the vacuum shaft 305. By connecting an air pipe inside the vacuum shaft 305, the voice coil is positioned on the vacuum shaft 305 by vacuum adsorption.

[0033] After the voice coil is positioned on the vacuum shaft 305, the reinforcing paper is fed onto the voice coil. Then, the first motor 303 is started to drive the drive wheel 304 to rotate clockwise. During the clockwise rotation, the first motor 303 can drive the driven wheel 306 to rotate via the synchronous belt 307. During the rotation, the driven wheel 306 can drive the vacuum shaft 305 and the voice coil to rotate, thereby winding the reinforcing paper onto the voice coil.

[0034] The abutting mechanism 5 includes a first L-shaped block 501 fixedly installed on the upper fixed plate 9, a first cylinder 502 fixedly installed on the first L-shaped block 501, a second L-shaped block 506 fixedly installed on the output end of the first cylinder 502, a slider 503 fixedly installed on the bottom of the upper fixed plate 9, a slide rail 504 fixedly installed on the second L-shaped block 506, and a pressure wheel 505 fixedly installed on the second L-shaped block 506. The slide rail 504 is slidably connected to the slider 503.

[0035] By activating the first cylinder 502, the second L-shaped block 506 is driven to move towards the vacuum shaft 305. During the movement, the second L-shaped block 506 drives the pressure roller 505 to press the reinforcing paper onto the voice coil surface, which ensures that the reinforcing paper is tightly attached to the voice coil.

[0036] During the movement of the second L-shaped block 506, the cooperation between the slider 503 and the slide rail 504 can prevent the second L-shaped block 506 from shifting.

[0037] The cutting mechanism 6 includes an overlapping plate 601 fixedly mounted on the upper fixed plate 9, a second cylinder 602 fixedly mounted on the overlapping plate 601, an L-shaped connecting block 603 fixedly mounted on the output end of the second cylinder 602, a guide plate 604 fixedly mounted on the L-shaped connecting block 603, a mounting block 605 fixedly mounted on the guide plate 604, and a cutting blade 606 mounted on the mounting block 605 by screws. The cutting blade 606 can be replaced by screws.

[0038] After the reinforcing paper is wound, the second cylinder 602 is activated to drive the L-shaped connecting block 603 to move towards the vacuum shaft 305. During the movement, the L-shaped connecting block 603 can drive the guide plate 604, the mounting block 605 and the cutting blade 606 to move towards the vacuum shaft 305. The reinforcing paper can be cut by the cutting blade 606.

[0039] The guide plate 604 has a guide groove in the middle that matches the guide rod 10. The top of the guide rod 10 guides the guide groove of the guide plate 604 and the upper fixing plate 9 from bottom to top and is fixedly connected to the base 1. Through the cooperation of the guide groove and the guide rod 10, the guide plate 604, the mounting block 605 and the cutting blade 606 can be prevented from shifting when they move.

[0040] The pushing mechanism 4 includes a second mounting column 401 fixedly mounted on the top of the L-shaped plate 2, a second motor 402 fixedly mounted on the second mounting column 401, a threaded rod 403 fixedly mounted on the output shaft of the second motor 402, a sliding plate 404 threadedly connected to the threaded rod 403, two guide columns 405 fixedly mounted between the base 1 and the L-shaped plate 2, guide bushings 406 fixedly mounted at both ends of the sliding plate 404 and adapted to the guide columns 405, a horizontal plate 407 fixedly mounted on the two guide columns 405, two sliding rods 408 fixedly mounted on the sliding plate 404, and a sleeve 409 fixedly mounted on one end of the two sliding rods 408 away from the sliding plate 404.

[0041] The end of the sliding rod 408 away from the sliding plate 404 passes through the horizontal plate 407 and the base 1 from top to bottom and is fixedly connected to the sleeve 409. The sleeve 409 is slidably sleeved on the vacuum shaft 305. The end of the threaded rod 403 away from the second motor 402 is rotatably connected to the horizontal plate 407 through a bearing.

[0042] After the cutting blade 606 cuts the reinforcing paper, the voice coil processing is completed. Then, the second motor 402 is started to drive the threaded rod 403 to rotate clockwise. During the clockwise rotation, the threaded rod 403 can drive the sliding plate 404, which is threaded to it, to move closer to the base 1. During the movement, the sliding plate 404 is guided by the cooperation of the guide bushing 406 and the guide post 405. During the movement, the sliding plate 404 can drive the sliding rod 408 to slide within the horizontal plate 407 and the base 1. During the sliding, the sliding rod 408 can drive the sleeve 409 to slide on the vacuum shaft 305, thereby pushing the processed voice coil out of the vacuum shaft 305 to complete the unloading.

[0043] In summary, when using this utility model, the voice coil is first placed on the winding mechanism 3, and then the reinforcing paper is fed onto the voice coil. The winding mechanism 3 drives the voice coil to rotate, thus winding the reinforcing paper onto the voice coil. During winding, the contact mechanism 5 presses the reinforcing paper against the surface of the voice coil, ensuring that the reinforcing paper adheres tightly to the voice coil. Then, the reinforcing paper is cut by the cutting mechanism 6. After processing, the finished product is pushed out of the winding mechanism 3 by the pushing mechanism 4 to complete the unloading. The entire process is automated, improving production efficiency.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
